How will these changes affect me?
Starting in early 2016 Office 365 Home, Personal and University subscribers will be cut to 1 TB OneDrive storage. If you are storing more than 1 TB in your OneDrive account, you will be notified to decrease your storage within the next 12 months. The 100 GB and 200 GB plans are no longer available to new users and will be replaced by a 50 GB plan. If you want to unsubscribe from Office 365 because of these changes, Microsoft offers a pro-rated refund.

But not only paid storage is affected. Also the free OneDrive storage is being down-scaled from 15 GB to 5 GB for all users. If you are using more than 5 GB space on OneDrive you will have one year to reduce the data below this limit. The 15 GB camera roll storage will be discontinued completely in early 2016. To see your plan and how much space you are using, visit the Manage Storage page.
